What is a Meter?
The international standard unit of length, approximately equivalent to 39.37 inches
A meter is a unit of length in the metric system. It’s used all around the world as the standard way to measure how long something is, like the height of a doorway or the length of a table.
One meter is a little longer than a yard and is equal to about 39.37 inches.
Originally, a meter was defined as one ten-millionth of the distance from the North Pole to the South Pole along the Prime Meridian (through Greenwich, England). Today, scientists define a meter more precisely: it's the distance light travels in a vacuum in 1/299,792,458 of a second.
Students often use meters when:
- Measuring the length of objects
- Solving problems involving distance
- Working with the metric system
When Do Students Learn About Meters?
Students begin learning about meters and the metric system in early elementary school, especially when working with measurement and length.
Grades 2–3 – Introduction to Meters
Students learn to estimate and measure lengths using metric units like meters and centimeters.
Grades 4+ – Using Meters in Problem Solving
Students convert between units, solve word problems involving metric measurements, and apply meters in real-world contexts.
